In this video I explain how to use a z-table or a standard normal table in order to calculate the percentage of scores below, above, or between z-scores for a normal distribution. Finding the areas under the curve associated with … Read More
The Standard Normal Curve, Empirical Rule, & Z-Scores
In this video I explain how we can use the equation for a normal curve to generate a probability density function and use that to estimate probabilities. While normal curves may differ in where they are centered and how spread … Read More
